(b) Screenshot of Block Data Information RegionFigure 14. Screenshots of execution results of simulation program
By analyzing simulation results, Fig. 15 shows the generation time of different block in simulation program. It can be noted that most blocks take exactly 15 minutes for generation process. This is because many sampling data in station/plant are required to transmitted to dispatch center for every 15 minutes according to electricity industry regulations. For the program implementation, a timer is used to trigger an interruption for generating new block. However, if users need to acquire data immediately, they can summon data through simulation program interface. Such occasions, which are called data summon events, happen on block 7, block 15, block 25 and block 35, and it can be seen the generation time of those blocks is less than 15 minutes. Moreover, due to the existence of program timer, the subsequent block after any of these blocks also possesses generation time less than 15 minutes.
